To alt whom it may concern.'

Be it known that I, ALFRED C. Econns, a citizen of the United States of America, residing in New York, in the borough of irooklyn, county oi Kings, and State of New York, have invented certain new and useful improvements in Rectal Syringes, of which the following is a specification.

This invention relates to that class of syringes which is used for irrigating the rectum and for flushing the colon, the syringe being intended to be used with a water-bottle by which the liquid for irrigaw tion is supplied; and for this purpose the invention consists of a rectal syringe comprising a water-bottle, a conoidal head, a stem inserted into the upper end of the head, a coupling for connecting the base of the head with the water-bottle, a vertical channel in the upper part of said head, two horizontal channels separated by a hori- Zontal partition in the head, said channels being connected respectively with the ver tical channel and with the coupling of the waterbottle, and a loop-shaped tube connected with the horizontal channels and provided with a spring-clasp for conducting the liquid under pressure from the water-bottle through the tube and channels et the head to the stem of the same.

ln the accompanying drawing, Figure l represents a plan-view of my improved rectal syringe, Fig. 2 is a side-elevation of the same, and Fig. 3 is a detail vertical transverse section through the head of the syringe, drawn on a larger scale.

Similar letters of reference indicate corresponding parts throughout the different igures of the drawing.

Referring to the drawings, o represents a water-bottle of any approved construction, which is provided at its center-portion with a coupling for applying my improved rectal syringe thereto. The coupling is formed of a threaded nipple c which eX- tends 'from a center-plate b1 of the bottle I) into an interiorly-threaded recess c1 in the base of the head a, so that a tightly-itting connection between the water-bottle and the head is made. The head a is preferably made of conoidal shape and provided at its upper part with a detachable stem (l, which is screwed into the upper end of the head.

The head a is preferably' made of soit rubber or other suitable material and provided with a central channel el in its upper portion, in line with the stem d, and with two horizontal channels in the body of the head a, said horizontal channels being separated by a partition a3, as shown clearly in Fig. 3. The upper channel a2 is connected with the central channel al and the lower channel a2 with the coupling c. The ends of the channels o2 are provided with screwnipples el to which is applied a loop-shaped liquid-conducting tube e, which can be opened or closed by means of a spring-clasp c2 of the usual well-known construction.

Willen. the rectal syringe is to be used, the water-bottle is filled with the liquid required and the stem of the syringe introduced into the rectum. The pressure eX- erted on the head of the syringe forces the liquid in the water-bottle through the coupling in the lower part of the head, the lower channel a2, the loop-shaped tube e into the upper channel a2 and then through the central channel t1 and the stem Z into the rectum, so as to produce the effective irrigation of the same and permit the supply of a considerable quantity of liquid through the rectum, which supply is regulated by the more or less continued pressure exerted by the body on the water-bottle.

When the rectal syringe is not desired to be used, it is unscrewed from the water-bottle and the coupling of the same is closed by a screw-cap, so that it can be used as an ordinary water-bottle. The screw-cap is removed when the water-bottle is to be used in connection with the rectal syringe, which is then replaced in position thereon and used as described.

The advantages of my improved rectal syringe are, first, that owing to the head being made of soft rubber, it dispenses with the expensive hard-rubber heads and valves for the same; second, that the direct pressure exerted on the head of the rectal syringe and on the water-bottle supplies the quantity of liquid required for irrigation' communicating with the Water-bottle, a stein on the body, a Channel in the body communicating With the stein, said Channels normally not communicating With each other, and a loop-shaped tube Connecting the channels for bringing` about a eonnnunication thereof.

In testimony, that I claim the foregoing as my invention, I have signed 1ny naine in presence of two subscribing Witnesses.
